Amazon, the internet’s largest retailer, is making an aggressive move into the booming and intensely competitive business of streaming music. The company will expand its Prime membership offerings by adding a stockpile of old and newish music for subscribers to stream on demand. The Prime music service, which is scheduled to launch this June or July, will not include recent releases but instead restrict its catalog to songs and albums that are 6 months old and older, five music industry sources familiar with the company’s plans confirmed to BuzzFeed. Similar to Prime Instant Video, the on-demand video option available to Prime members, the Prime music service (the official name of which is still unknown) won’t aspire to the full universe of existing content, instead offering a potluck of select songs and albums it has licensed from labels at a discount.
